The water-resistant Nautilus ref. 3700
The case patent design of the first Nautilus, reference 3700⁄1, was registered on 23 April 1976. It comprises two parts, the main body and the bezel, surrounded on each side by “ears”. The two parts are both secured by lateral screws. A rubber seal sits between the bezel and case body, thus compressed when subject to water pressure, and forming a perfect watertight seal. From 1976 until 1980, the cases were made for Patek Philippe by Favre-Perret SA, Le Crêt du Locle. In 1980, Patek Philippe started manufacturing cases and bracelets in their Ateliers Réunis workshops, and the Nautilus then changed its reference number to the new ref. 3700-11.
Ref.3700 is illustrated in the 'Blue Book 4', 2020 edition by Eric Tortella, page 407
